Introduction

The Lockheed Martin F-16 Fighting Falcon, developed in the 1970s, is one of the most successful and widely used fighter jets in the world. It has served in over 25 air forces, including that of the United States, Israel, Pakistan, Egypt, and South Korea.

On the other hand, the HAL Tejas is a fourth-generation lightweight, multi-role combat aircraft developed by India’s Hindustan Aeronautics Limited (HAL) under the Light Combat Aircraft (LCA) program. It is a symbol of India’s push for self-reliance in defense manufacturing and an answer to regional threats.

Overview: F-16 Fighting Falcon

Developer: General Dynamics / Lockheed Martin (USA)
Maiden Flight: 1974
Introduced: 1978
Generations: Fourth-generation, with multiple upgrades (Block 50/52, Block 70/72 Viper)
Roles: Air superiority, ground attack, SEAD, recon

The F-16 has undergone various upgrades since its inception, including modern avionics, Active Electronically Scanned Array (AESA) radars, and more advanced weapons systems. It has a proven combat record and is known for its agility and affordability compared to heavier fighters.

Overview: HAL Tejas LCA

Developer: Hindustan Aeronautics Limited (HAL), Aeronautical Development Agency (ADA), DRDO
Maiden Flight: 2001
Introduced: 2016 (Tejas Mk1), further variants under development
Generations: 4+ generation
Roles: Interception, ground attack, air-to-air and air-to-ground combat

Tejas is India’s first indigenous supersonic fighter aircraft, developed as part of a national mission to replace aging MiG-21s. It is compact, agile, and loaded with modern avionics, composite materials, and a fly-by-wire control system.

Design and Airframe

F-16:

Length: 15.06 m
Wingspan: 9.96 m
Empty Weight: 8,570 kg
Max Takeoff Weight: 19,200 kg
Airframe: Aluminum alloys, titanium, carbon fiber in later versions
Design: Bubble canopy, blended wing-body

Tejas:

Length: 13.2 m
Wingspan: 8.2 m
Empty Weight: 6,560 kg
Max Takeoff Weight: 13,500 kg
Airframe: 45% carbon-fiber composites, reducing radar cross-section and weight
Design: Tailless delta wing design

👉 Verdict: Tejas is lighter and more modern in design, with significant composite usage, but F-16 has a larger payload and fuel capacity.

Avionics and Cockpit Systems

F-16:

Advanced digital fly-by-wire system
Upgraded versions feature AESA radars (AN/APG-83)
Wide-angle HUD, MFDs, and pilot-friendly glass cockpit
Helmet-mounted cueing system

Tejas:

Indigenous open architecture mission computer
Multi-function displays, digital flight control system
Israeli EL/M-2052 AESA radar (Tejas Mk1A)
Helmet-mounted display system (HMDS)

👉 Verdict: Tejas features state-of-the-art cockpit ergonomics and indigenous software architecture, though the F-16 has proven combat-tested avionics.

Engine and Performance

F-16:

Engine: Pratt & Whitney F100 or General Electric F110
Thrust: ~28,000 lbs with afterburner
Max Speed: Mach 2.0
Range: 4,220 km (with drop tanks)
Service Ceiling: 15,240 m

Tejas:

Engine: GE F404-IN20
Thrust: ~19,000 lbs with afterburner
Max Speed: Mach 1.6
Range: 1,850 km (combat radius ~500 km)
Service Ceiling: 16,000 m

👉 Verdict: F-16 has better raw thrust and speed, but Tejas Mk2 will feature the more powerful GE F414 engine, narrowing the gap.

Weapons and Payload

F-16:

Payload Capacity: 7,700 kg
Weapons:
- AIM-9 Sidewinder, AIM-120 AMRAAM
- AGM-65 Maverick, JDAM, Paveway LGBs
- 20 mm M61 Vulcan Cannon
- Harpoon, HARM missiles

Tejas:

Payload Capacity: ~4,000 kg
Weapons:
- Astra BVR missiles, Derby, Python-5
- Smart bombs, laser-guided bombs
- Russian Kh-59, Israeli Spice 2000
- 23 mm twin-barrel cannon

👉 Verdict: F-16 can carry a wider and heavier weapons load; however, Tejas is catching up with indigenous and Israeli missile integration.

Radar and Sensors

F-16 (Block 70/72):

Radar: AN/APG-83 SABR AESA
Capabilities: Simultaneous air-to-air and air-to-ground tracking, advanced ECCM

Tejas Mk1A:

Radar: EL/M-2052 AESA (by IAI)
Capabilities: Multi-target tracking, BVR engagement, synthetic aperture radar

👉 Verdict: Both aircraft now use AESA radars, a key element in modern air combat.

Operational History

F-16:

Combat-proven in Gulf War, Kosovo, Afghanistan, Syria, Iraq, Pakistan
